Hibernate not inserting rows

[Rav Nomula]

I able to generate the schema but when I try to insert, I am getting the error com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'id' cannot be null. My Phone table primary key is a composite key consisting of phoneNumber and foreign key id.

I have my classes as below

The way I have the schema, I have id column in Phone table as both primary key and foreign key to Student table and its failing while trying to perform an insert. How can I get this to work? Below is from logs.

Anybody?? Is my schema wrong? Please advice!!

[Saif Asif]

Greetings Rav,

I just took a glance at all that code, I didnt go in the details but according to your hibernate logs ,

Hibernate: create table Phone (phoneNumber varchar(255) not null, color varchar(255), id integer not null, primary key (phoneNumber, id))

The table Phone is created with coloumn 'id' as not null , however when inserting a new record in the this table you are doing it like

        Phone ph1 = new Phone();  
        ph1.setColor("Black");  
        ph1.setPhoneNumber("1111111111");  
  
        Phone ph2 = new Phone();  
        ph2.setColor("Blue");  
        ph2.setPhoneNumber("2222222222");  
        phones.add(ph1);  
        phones.add(ph2);  
       
        //Where is the non-null parameter ID that needs to be passed ???

Hibernate will be expecting that you specify an appropriate value for couloumn 'id' as well otherwise it will fail at the binding process like it is as seen in your logs below

Hi Asif,

Thanks for your reply but shouldn't id column value of Phone table be auto inserted from the student table id value? Its a foreign key to the student table too.

Hibernate: alter table Phone add index FK_aoj0eivd0ap3drxnoyk4xj10q (id), add constraint FK_aoj0eivd0ap3drxnoyk4xj10q foreign key (id) references Student (id)

I want all the inserts to happen from the student side and not from both sides. How do I make this happen?

[Saif Asif]

I found this take a look at it , it might be useful. Also , Why not use cascading for that matter ? Hibernate Cascading for saveOrUpdateOrphan

[Rav Nomula]

Hi Asif,

In my student.java class I am already doing the below

@OneToMany(cascade = CascadeType.ALL)  
@JoinColumn(name = "id")  
private Set<Phone> phones;  

[Ranchhor Das]

Hi Rav,

I am also facing the issue.

How did you resolve it?

Thanks in Advance!!!
